Problems solved by technology

The disadvantages of hub motors are small power density, large volume, low speed, and small transmission torque, so it is difficult to adapt to complex roads in mountainous areas
In response to this problem, some manufacturers have made the in-wheel motors larger and larger. Although the power has been increased, this will lead to large energy consumption, short mileage and high heat generation of electric vehicles or electric motorcycles on urban roads. , the life of the motor is short, and the cost is also high

Abstract

The invention provides a laterally-arranged gear shifting motor assembly used for an electric vehicle or an electric motorcycle. The laterally-arranged gear shifting motor assembly comprises a motor and a wheel hub which are arranged on a vehicle frame. A speed changer is arranged between the motor and the wheel hub. The motor is connected with an input shaft of the speed changer. The wheel hub is connected with an output shaft of the speed changer. A magnetic encoder is connected to the motor. When the whole vehicle operates, an appropriate gear is selected according to the change of the load condition of the wheel hub. The motor adopts a high-speed permanent magnet motor and is provided with the high-precision magnetic encoder, the precision is high, the stability is good, and motor vibration is small. Liquid gear oil is adopted for cooling and lubrication of the speed changer, transmission noise can be effectively controlled, and the transmission efficiency is improved.

Description

technical field [0001] The invention relates to a motor assembly, in particular to a side shifting motor assembly for an electric vehicle or an electric motorcycle. Background technique [0002] At present, the motors on electric vehicles and electric motorcycles commonly used in the market mainly include hub motors. The disadvantages of hub motors are small power density, large volume, low speed, and small transmission torque, so it is difficult to adapt to complex roads in mountainous areas. In response to this problem, some manufacturers have made the in-wheel motors larger and larger. Although the power has been increased, this will lead to large energy consumption, short mileage and high heat generation of electric vehicles or electric motorcycles on urban roads. , The life of the motor is short, and the cost is also high. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the existing defects and provide a ...
